\(AB=BD=6\), \(\angle ABD = 90°\)
Quantity A |
Quantity B |
\(\angle DBC+ \angle BCD\) |
\(90°\) |
A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.
Kudos for
R.A.ESince \(\angle ADB = 90°\), therefore\(\angle BDC = 90°\)
Now in \(\triangle DBC\), we have
\(\angle BDC = 90°\)
and as the sum of angles in a \(\triangle\)add up to 180°
therefore
\(\angle DBC+ \angle BCD = 90°\)
Hence option C
